To all whom it my concern:

2' Be it known that L'FRANK Tyson, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Ice-Cream-Fr'eezer Heads, of which the following'is'iaspecification.-

The invention relates to the head ofan ice cream freezer of the horizontal cylinder type having rotating agitating and ejecting means therein, and the object of the im movement is to provide a combined inlet and outlet guard-wall onthehead by means of which the liquid cream can be introduced into and the frozen cream ejected from the freezing chamber through a single openin located -i'n the lower portion of the head Ice cream freezers of thi's type have been made with a head having an opening in the upper portion with an'extern'al guard or;

hopper through which the liquid cream may be fed into the freezing cylinder and into which the frozen cream can overflow and be observed by the operator, which opening has unnecessarily weakened the upper por'-' tion of the head; and furthermore difiiculty has arisen from a splashing of the liquid cream through the opening and out of the hopper, caused by the proximity of' the opening to the surface of the liquid cream and the rotation of theagitating and ejecting means within the freezing chamber. These ditlioulties are overcome by using'a single opening in the lower portion of the head and providing a common guard wall, the upper portion of ,which is flared upward and serves as an inlet and sight hopper, while the lower portion is flared downward and serves as an outlet mouth,,which mouth is provided with a valve as usually employed in machines of this type. i

The invention, thus set forth in general terms, as embodied-"in a/preferred form thereof, is illustrated in the accompanyin drawing, forming part hereof, in which- Figure 1 is a front elevation of the ice cream freezer cylinder showing the improved head thereon; Fig. 2, a vertical section of the same on line 2-2, Fig. 1; Fig. 3, a fragmentary transverse section of the head on line 33, Figs'. '1 and 2; and Fig. 4, a fragmentary transverse section of the head on line t4 Figs. 1 and 2.

' Similar nun'ierals refer to similar parts throughout the drawing.

ably extends from the end'thereof. The opening ,17 is provided divided by'thespiralflanges 7 to: rm a --spiral duct. The forward head 8 of'the cylinder is composed of a icircular late which issecured in therabbet of the ring 1 as by means of the screwed clamps 9, in the center of which plate is formed or secured the axial socket 10 adapted 'to receive the screw-bearing 11 for the pivot-piii' 12 re ceived in the'forward end of the rotatable shaft or tube 13 to whi clithejarms l' t of the I agitating and ejecting meansare secured.

The external guard wall 15'is'formed or secured, as b means ofthe screws 16, on

the forward ace of the headS, and preferupper tothe'lower in the lower orti'onpf the forward head '8 of the cylin' er, fwh'ich opening 'is'flocated ;within the sidewalls of the-lowertport'ion of thfig ard wall 15-} and the guard wall is preferably flared upward from a point 18.'

-. opposite the upper end of the opening to form the inlet and sight hopper 19, and alsodownward from the same point 18 to form the outlet mouth 20, although any particular flared shape.for the guard wall iisnot essential. The mouth of the outletli's' nor;- mally closed by the valve 21 which is adapted to beopened and closed by'moans ofthe connecting bar; Q Qand the lever-23 pivoted to the forwardly projectingbearing lug 24 formed or secured on the guard wall.

In use of the freezer, liquid cream "is poured a into the inlet hopper and flows downward into the reezing chamber through the opening 17 in the lower portion of the head-thereof until the cylinder is filled to the desired height, which is gen era-11y about the middle on axis thereof, and it is evident that if no vent is provided the elasticity of the air in the cylinder .will permit the liquid cream. to rise to the mid:

;dle thereof'before being trapped above the opening. The freezer is then -operatedin the usual manner for congealing the cream, during which process the rotatnlg means;

- is evident that the ward through the opening into the lower agitates the contents ofthe cylinder, and it same is free to flow outportion of the hopper, but that the location of the opening in the head below the level of the liquid cream serves to prevent any undue splashing of the same by the rotation of the; agitating means. And furthermore that, when the cream has been congealed, the same may be viewed and inspected through the upper end of the hopper 19;

and the lower end'of-the hopper, which discharge is efiected by the rotation of the agitating and ejecting means in the usual manner.

I claim:

A horizontal-cylinder ice-cream freezer head having an opening in its lower portion, andhaving an external guard wall forming a hopper extending upward from the opening, said wall extending downward past the opening thus forming an outlet mouth below the opening, and 'a valve in the outlet mouth.
